Printed twice with same results. I didn't lower the rating because I believe maybe if I changed the orientation to face the fan it would've print fine.
My son still loves it...I told him it went through a bit of turbulence!! 🤣
I have not had this issue, and you can see from the comments that other colleagues also managed to print the model. I would suggest to perform a full maintenance cycle (including a cold pull). Some time ago my prints were not fine. I changed the hot end, ran a full maintenance cycle, and all issues were fixed
I printed one of these for work and it was great. They also made me a 6500 series as the engines and number of windows are different. But thanks for the great print!
